This 1.31ct lab-grown marquise sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VS1 clarity (very-slightly-included), with a very-good cut grade and certified by IGI LG835609095 or 835609095. Listed at 20 retailers as of October 25, 2026, with prices from $217 to $1,175, a $958 spread on the same certified stone. Reve Diamonds lists it at $1,175. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
